Electrical components

No doubt you have been shocked when touching a metal object.

This is due to the electrostatic charge in the human body. This charge can cause malfunctions if you touch the electric steering box and steering column components.

  • Before working on electrical components, touch an earthed object, such as a water pipe or a lifting platform. Do not directly touch connector contacts.
